The Indian meal moth Plodia interpunctella is a pest of stored products worldwide. Plant‐derived essential oils with insecticidal activity could be safe products to control this species. The scarce information about the mode of action of most plant‐derived products limits their use for the control of insect pests. Here, we demonstrate that an essential oil distilled from Lippia turbinata (?poleo?) has insecticidal activity on P. interpunctella larvae. Furthermore, we performed a comprehensive characterization of P. interpunctella neuroendocrine system, in comparison with other lepidopteran species. HIGHLIGHTS ? Lippia turbinata essential oil has a potent insecticidal activity on Plodia interpunctella larvae. ? Characterization of P. interpunctella neuroendocrine system has been performed. ? Most characteristics of this system are conserved among Lepidoptera.
